'59 rear axle bearing---need crossover reference

[George W.]

My '59 rear axle bearing housing has a 3" diameter cavity that is 7/8" deep (no shim).
The replacement bearings are 3.0" x 1.0" thick.
I need the original maker(s) identification number and/or the exact dimensions/specifications for the 7/8" bearing so I can find a substitution. Need retaining ring also.
The bearing removed is 7/8" with one o ring, ball bearing type, with the oil seal (6971-s) on the out board side.
Thank you,
George

Here's what GM says: originally, there were two bearings, one for cars with positraction and one for cars without posi:

original for cars with posi---GM #7451112, aka Hyatt JRN1542-WAB-23. This bearing was discontinued and replaced by GM #7451415. The latter was discontinued and replaced by GM #907294, aka New Departure RW-607BRSY1Z. The 907294 is also now discontinued.

original for cars without posi----GM #3746787, aka New Departure RW607SY12. This was discontinued and replaced by the same GM #907294 as shown above.

The BCA replacement for the 907294 is RW607NR.

Humm?
My center pig is a posi, but it seams I have a non posi carrier?
So, the non posi bearing is the 7/8" deep by 3" diameter Bering?
thanks again

Sorry, I don't have dimensional specs on these bearings. Perhaps someone else will have the answer.
